After Fan Miaomiao finished speaking, Zhang Leifeng took two steps back.

She walked past Zhang Leifeng: "Thank you." He whispered.

Boom!

Zhang Leifeng closed the door.

As soon as Fan Miaomiao turned around, Zhang Leifeng suddenly stretched out his finger and stabbed her heart.

Fan Miaomiao, don't be so frightened that she almost sat on the ground.

looked at Zhang Leifeng in horror: "What are you doing?" Scared the hell out of me. Grumbling.

Zhang Leifeng smiled and clapped his hands: "Hahaha, it seems that this question is still very simple." A muttering sound of excitement came out of his mouth.

Fan Miaomiao frowned and walked up to him and slapped him the back.

Zhang Leifeng, who was in pain, bared his teeth.

"Let you scare me." Fan Miao said with a pout.

Zhang Leifeng shook his head, took out his mobile phone and dialed Xing Dongjie's number.

"Next time, please use your brain when you encounter a case?" Don't say anything, lose a meal first.

As soon as Xing Dongjie heard this, he knew that Zhang Leifeng had already solved the case. Who's amazing, bear it.

"Okay, okay, next time I use my brain, what is the situation in this case?" It was the first time for Xing Dongjie to cooperate with himself like this, but Zhang Leifeng still felt a little unaccustomed to it.

"Before I tell you the answer, I'm going to give you some popular science knowledge, listen up." Zhang Leifeng put on a teacher's face and said proudly.

Xing Dongjie on the other end of the phone took a deep breath and replied patiently: "Okay, Mr. Zhang, I have prepared the book and pen, please advise." ”

"First of all, you have to know that it is not easy to stab the heart with a knife, because there are ribs and sternum blocking it, but the murderer can be stabbed with a knife, what does it mean?"

Xing Dongjie suddenly realized that he really hadn't thought of this matter.

"It shows that the murderer knows very well the location of human organs." replied.

"And if we assume that a very small fruit knife actually stabs the heart, the following things will happen:

1. Myocardial penetrating injury, penetrating wall injury. At this time, your circulatory system has been damaged, and even if you pull out the knife slowly, the blood will be pressed out of the heart muscle, in other words, it will cause heavy bleeding, which can be as fast as a few minutes, and as slow as dozens of minutes will cause death.

2. Pericardial penetrating injury + myocardial non-transpenetrating injury. If it is median, the pericardial damage is small, and regardless of the size of the myocardial damage, the pericardial effusion can compress the heart so tightly that it cannot beat. If you make a large enough incision on the side, although the problem of pericardial effusion is avoided, the damage to the heart muscle will also cause you to die quickly.

3. Pericardial injury only. This is the luckiest of all cases, the heart is cut open, the pericardial effusion does not kill people immediately, if it is a non-penetrating pericardial injury, the effusion is in the mediastinum and not in the pericardium, the effect on the heart will not be immediately apparent, so in this case, you may live for a few days, enough to support you to go to the hospital for rescue. ”

Xing Dongjie was dumbfounded when he heard this, he really didn't expect this guy to know this kind of knowledge.

"You mean that someone who knows a lot about human organs assassinated her and then made her bleed to death in a short period of time?" Xing Dongjie said.

Zhang Leifeng nodded: "Yes." ”

"Where did the murderer do it?" Xing Dongjie asked.

"Where in the mall there aren't cameras?"

"Where are there no cameras? The cameras in the mall are almost full. Xing Dongjie hadn't figured it out for a while.

"You're really going to be stupid, do you have a camera in the toilet?" Zhang Leifeng's truth passed through the phone to give him a brain collapse, and all the rust in his brain popped out.

Syllable!

I heard the sound of Xing Dongjie slapping the table.

"I didn't think of that." Some shouted excitedly.

Zhang Leifeng Nunu hung up the phone and threw the phone on the table.

Xing Dongjie immediately sent someone to call up all the surveillance in the mall that day, and used the surveillance to track the deceased.

The deceased entered the mall alone at 10.20am, at which point she behaved normally and did not appear suspicious.

Take the escalator to the second floor and enter a clothing store, where I spent about forty minutes carrying two bags.

Then enter the shoe store.

At 12:26 p.m., I entered the snack area on the fourth floor of the mall, ate something here, and left at 1 o'clock.

She then took the escalator down the ladder.

When I came to the second floor, I found that she had quickened her pace, as if something was wrong.

Xing Dongjie stared at the screen with his eyes fixed on this, and saw the signs hanging above the mall through the surveillance display, and the place where the deceased went was really a toilet.

The monitoring is broken in the passage of the Tongxiang toilet, and there is a blind spot for monitoring.

Syllable!

Xing Dongjie slapped the table with his hand a little disappointed.

Eight minutes after she was inside, she walked out clutching her chest, by which time the bag in her hand was gone. Xing Dongjie zoomed in on the surveillance footage and saw blood flowing from the tips of her fingers, and her other hand seemed to be groping for something in her pocket.

Thump!

Two minutes later, she fell to the ground, at which point passers-by surrounded her and called the police and emergency services.

By the time the doctor arrived, she had died of blood loss.

Seeing this, Xing Dongjie turned his gaze back to the toilet.

"Could it be that the murderer is a woman?" The police officer on the side muttered quietly.

Xing Dongjie was also thinking about this problem, because the deceased entered the women's toilet, and if a man walked into the women's toilet, no one would find out.

He looked at the surveillance twice from beginning to end, but still didn't find anything suspicious.

Jingle bells! Jingle bells!

A phone ringing on the table.

Pick up your phone and connect to the call.

"Did you find it?" Zhang Leifeng wanted to know the final answer.

"No, she did die after coming out of the toilet." Xing Dongjie replied.

Zhang Leifeng took a deep breath: "Don't tell me it's like this, you still haven't found the murderer?" ”

"Congratulations on your correct answer, I just haven't found it."

"Hey, really...... You now immediately look up the "woman" who entered the toilet five minutes before she entered the toilet, and then compare who did not come out of the toilet or was in the toilet for too long. ”

Zhang Leifeng thought to himself, I've already said it here, if you still can't find the murderer, the captain of the criminal police can really be replaced by someone else.

Xing Dongjie rolled his eyes angrily and hung up Zhang Leifeng's phone, and began to inquire as he said.

It was eventually discovered that nine women had walked over five minutes before the deceased had entered the toilet, but all nine had come out within five minutes of her accident, but one had changed his clothes.

The most important thing is that she didn't even look at the deceased after she left the toilet, and walked directly to the other side, you must know that everyone has curiosity, and it is impossible to leave without looking, which made Xing Dongjie confirm her suspicion.
